Remarks :
1) A sixth order FD derivative can not be used with too strong gradients

2) The grid (xp) is generated inside the pade_init function. A slight modification would authorize external grids but beware to the boundary conditions

.m files in the package:
- pade_init.m : initialization of the Pade coefficients
(a tridiagonal matrix is inialized)

- pade_firstder.m : first order derivative
- pade_secder.m : second order derivative
- pase_test.m : use this function to carry out some tests.
